Sericostomatidae
Stephens, 1836
Bushtailed Caddisflies
Genus Guides
2is a of caddisflies (Trichoptera) commonly known as bushtailed caddisflies. The family comprises approximately 19 and at least 90 described . Larvae construct portable cases using silk and environmental materials. The family has a global distribution with notable diversity in the Palearctic region, including species in the Balkans, Iberian Peninsula, and Madagascar.

Habitat
Freshwater stream and river . Larvae inhabit lotic environments, with specific documented from mountain streams in Central Greece, the western Alps, Apennines, and coastal mountain streams in California. Some species show bioclimatic preferences for Mediterranean and temperate montane conditions.
Distribution
Widespread across multiple biogeographic regions. Documented from: European Ecoregion 3 (Italy, Corsica, Malta), European Ecoregion 6 (Hellenic western Balkan region, specifically mountains of Central Greece), French, Italian, and Swiss western Alps, Apennines, Iberian Peninsula, Turkey, Caucasus, Transcaucasia, Iran, Madagascar, and North America (including California and Canada). Northernmost South American record from Roraima state, Brazil.
Diet
Larvae function as , consuming leaf litter. Schizopelex festiva has been documented feeding on conditioned chestnut and oak leaves.
Life Cycle
Sericostoma personatum exhibits a three-year in Danish springs, with growth retardation observed during winter months attributed to lower temperatures. A 1.5-year life cycle has also been reported for this in other , with food quality and temperature suggested as explanatory factors.
Behavior
Larvae are case-builders that construct portable cases incorporating silk and environmental materials. Gumaga nigricula larvae demonstrate sedentary during low-flow periods, with most individuals remaining within 4 m of release points after 24 days. During high-flow events, downstream increases, with dispersal distances of 18 m and maximum recorded distances of 222 m for larvae, and up to 436 m for pupae.
Ecological Role
functional group in stream , processing leaf litter and contributing to nutrient cycling. As shredders, they influence energy transfer and organic matter breakdown in freshwater . Secondary salinization negatively affects performance through reduced metabolic rates, with potential cascading effects on stream food webs.
Human Relevance
Used as bioindicators for freshwater health and stream quality assessments. Molecular identification tools are increasingly employed to resolve cryptic and prevent erroneous biodiversity assessments. Sensitive to anthropogenic stressors including water salinization, which reduces survival, growth, and feeding .
